In order to perform the \(T\rightarrow 0\)  limit we choose a different
but related work theorem which is Crooks fluctuations theorem
[1]}, [2]}. The advantage will be that it allows to
derive an equality that can be extrapolated to the \(T\rightarrow 0\) 
limit. This theorem can be written as:
\(\frac{P_F(W)}{P_R(-W)} = e^{\beta (W-\Delta F)}\)
